Evaluation of glomerular filtration rate estimation through plasma clearance of iohexol in seagulls (Larus michahellis).
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCurrent endogenous indicators utilised in avian medicine are not sensitive enough to detect renal disease in its early stages. Alternative markers ought to be examined as a result. The aim is to investigate the accuracy of limited-sampling models for glomerular filtration rate (GFR) in adult seagulls using plasma clearance of iohexol (IOX).
resultsWe compared the GFR estimated from the plasma concentration of IOX at 3 sampling times, known as limited sampling models, with that estimated from the plasma concentration of IOX at 6 sampling times (reference model). The reference model's mean ± SD for GFR was 6.88 ± 2.46 mL/min/kg and did not considerably differ from the GFR predicted by the limited-sampling models. Model 4, in which GFR was estimated using plasma IOX concentrations at 5, 15, and 90 min after IOX administration, had the smallest GFR bias compared to the reference model.
conclusionsThe findings revealed that IOX plasma clearance was a reliable, accurate, and clinically applicable approach to calculating seagull GFR. This strategy might help with the validation and subsequent development of clinical renal biomarkers.
